What is Helvest Flex

Helvest Flex is a modular system designed for the control of model railroads, designed to be extremely flexible and customizable. The model railroader can adapt it to his needs by rationalizing purchases, space, and the need for electrical connections on the layout: in fact, each board can be assigned the functions you want by simply installing the corresponding modules. Even for those who are not experts in electronics or information technology, the configuration of a Helvest Flex system is very simple, because just plug the modules into the appropriate connectors and the equipment is ready for use on the plant. Other modules with new functions will be marketed periodically.

Working principle

Any electronic board that manages accessories or trains on the layout must communicate on the one hand with a control system (which can be the digital control unit, the PC, or some other electronic device) and on the other hand with the accessories or systems on the layout (e.g. by activating turnouts and signals, detecting the presence of trains, etc.). Helvest Flex offers two families of modules corresponding to these functions: - The "net" modules communicate with the control system; - Layout" modules control accessories and devices on the model railroad. Both modules are installed on the "HP 100" motherboard, which manages the whole system.

By choosing the desired modules you can then build a customized system, flexible, editable over time, easy to use.

Why choose Helvest Flex

You can configure the system as you like; You can modify the system with little expense; In the future it will be kept up to date with the latest technology; The system is easy to use and has many functions; In case of failure, damage or deterioration you can replace only the single module. Respects the environment thanks to the possibility of repair and our end-of-cycle product recall system.

How to setup an Helvest Flex system

The configuration of the desired functionality is very simple as it is sufficient to assemble the desired combination of modules "net" and "layout". The motherboard recognizes them and the device is ready for operation. The accessory obtained is adjusted according to the usual modes of the device. For example, if you assemble a DCC decoder for accessories, it is used like all the other DCC decoders, programming the CVs with the digital control unit. Of course, with the additional flexibility of being able to compose different functions by combining the modules "layout" at will. The adjustments and programming allow the flex system to be customised and fine-tuned in order to satisfy even the most demanding users.

Informations and customer care

Operation and configuration are very simple as described in the previous paragraph. Helvest is strongly committed to simplifying and clarifying the use of the system for absolute beginners. On the site are available information, guides, online tutorials for both the choice of modules and their use. If you have any doubts or questions, please do not hesitate to contact Helvest through the contacts indicated on the site. We will be glad to help you and make the instructions always clearer.

For the most demanding people...

For experts in electronics, computer science, makers, hackers and geeks: we have what you need! For Helvest, satisfying the user's needs also means creating a system that allows those who like to "get their hands dirty" to be satisfied as much as possible. The Helvest Flex modules lend themselves to a wide range of experimentation and modification possibilities, for those who want to customize even more. We specify that any intervention to the hardware and software will invalidate any form of warranty, and that Helvest can not provide any assistance on these operations. However, the modularity is also designed to facilitate the experiments: thanks to the low price of the individual elements, any "accidents" due to the experiments can be fixed with little expense by replacing only the module that should be damaged. The examples of what can be done are practically endless...: - with two welds and few cuts to the connectors you can change the modules to be powered independently; - all logical levels of the "net" and "layout" modules are compatible with the Arduino platform, so you can use them as add-ons for experiments or do-it-yourself devices. - The HP-100 motherboard is programmable with Arduino's language via an ISP connector. Keep in mind that overwriting the original firmware precludes, in almost all cases, the possibility of restoring the factory firmware.
